Hi Julie & Guitar Lady
What to wear New Year's Eve? I suggest you wear your posh frock to The Perlan and take your boots, hat, coat, gloves etc which can be stored at your table until required for the trip to the bonfires. You'll soon warm up at the bonfire as it is enormous - we only visited one three years ago. And when you are watching the fireworks, outside if you wish at midnight, you won't notice the cold as you'll be carried away with this spectacular event. Hope this helps.
